pplication led January 5, 1899.

T0 all whom it may concern: Beit known that I, FRANK THEoDoEE WIL- LIAMS, a citizen of the United States, residing Connecticut, have invented certain new and useful Improvements in Lamp-Burners, of

My invention relates to an improvement in lamps, especially in those of the centrahdraft type; and my object is to improve the construction thereof.

` Figure 1 is a side elevation, partly in sec- "on, of my device. Fig. 2 is a similar View ith the parts slightly in different position.

In the preferred form of my invention shown in the drawings, l represents the fount slightly higher than the inner one, and 4 a wick moving between the same.

5 is a spreader substantially in the form of a perforated cylinder, ittin g in this embodiment within the inner wick-tube and having a ilange 6 attached thereto and extending out over the wick and resting thereon, thus consense that the spreader is moved by the movement of the wick. As the Wick is moved up and down the spreader is moved with it, and when the wick is drawn down inside the wicktubes this flange 6 will close the opening between the tubes and extinguish the llame. The spreader has an inward bend 12 above its lower end, in this embodiment opposite the flange 6. This gives a greater space between the inner side of the wick and the outside of the spreader than if this spreader were of the same size from the bottom up and allows the vapor and llame to burn from each side of the wick up through a space 13 between llange 6 and the spreader. This relame can act on each. side of the wick the wick need not be turned so high for a given flame as in a construction where the flame can burn from only one side of the wick. This inward bendalso provides a space in which air from the spreader can mix with the vapor coming from the inner side of the wick. The ilange 7 projects from the upper part of the spreader, and below and close to it is an- SPEGIFICATION forming part of Letters Patent No. 628,424, dated July 4, 1899.

Serial No. 701,236. (No model.)

other flange 8, and between these flanges is a row of perforations 9. Y Y

Projecting up through the inside of the inner tube is a stationary rod lO, passing through a hole in the top of the spreader and carrying at its upper end a stop ll. When the height of the wick is determined which will give the most satisfactory llame, the stop 11 is placed in such a position on the rod lO that when the wick has been raised to the said height the top of the spreader will come in contact with the stop and the wick cannot be raised higher. p This provides a stop for the wick and prevents the wick being turned too high.

Other advantages will appear from an inspection of the disclosure herein, and I do not desire to limit myself to the construction l. In a device ofthe character described in combination, an inner and an outer tube forming between the same-a passage in which a wick is adapted to move,a movable spreader andastationary stop therefor within said inner wick-tube.

2. In a device of the character described an outer and an'inner wick-tube, a perforated spreader movable with relation thereto and having an inward bend near the lower part of the same, and a ilange carried by said spreader so as to be movable therewith and located near said bend, said spreader and flange having a space between the same for the escape of vapor.

3. In a device of the character described an outer wick-tube, an inner wick-tube, the top of the latter being slightly below that of the former, a perforated spreader located within said outer tube and movable with relation to both said tubes, said spreader carrying a flange adapted to it within said outer tube and act as an extinguisher, there being a space between the inside of said flange and the outside of said spreader.

4. In a device of the character described in combination a fount adapted to contain a liquid fuel, a wick-tube extending above the same, a second wicktube smaller than the former also extending above the fount and contained in said outer tube so as to leave a IOO space between the same for the passage of when said spreader is raised to aet as a stop the Wick, a perforated cylindrical spreader, therefor.
